Congratulations on the best Duncan Keith trade I have seen on this website. I still probably wouldn't do it as Edmonton, I'd rather try to just dump the Neal deal since Keith'll probably be a pain to dump, what with the NMC and all, but at least it's about fair value. Beyond that:

1. I wouldn't put Hyman with McDavid. McJesus is the god of the rush, the breakaway, and the array of dangerous chances that a team can generate off of controlled entries, while Hyman belongs to the heretical sect of the forecheck, the cycle, and the dreaded dump and chase. I get the theory of Hyman's playdriving keeping McDavid in the offensive zone, but he's probably better used to try and help another line drive play, given that the bottom-6 is still looking pretty ugly.
2. Erik Haula is not the player he was in Vegas. His defence has fallen off hard, and Evolving-hockey has him as a sub-replacement player over the last 2 years.
3. Cogliano's a really clever add, I don't think he can salvage Haula and Kassian on the third line, but him, Hyman, and ideally someone with a bit of finish could be a really solid line.
4. That's a lot to give up for a player that might be completely done. Even if Senko's healthy, to be worth Puljujarvi he'd probably have to return to his 2017-18 form, which seems like a really optimistic bet. Not necessarily impossible, but I'd probably just keep Jesse.

Overall, this team is still really shallow, 2/3 of the bottom-6 is replacement level or worse, the D corps is still below-average with Bear having to carry the boat anchor that is Duncan Keith, and with no first rounder, no cap and one of their best young players gone, there isn't exactly a clear path for improvement.
